Tolling in Colorado

HOV/tolled Express Lanes maximize the efficiency of HOV lanes. HOV/Express Lanes allow those who drive alone (also known as "single occupant vehicles") to use the HOV/Express Lanes if they pay a toll. As the HOV lanes have excess space, there is still room for additional vehicles without any travel time impacts to carpoolers to use these lanes without paying a toll. However, those who drive alone will now have the option of paying a toll.

The E-470 Public Highway Authority ("Authority") consists of eight member jurisdictions: Adams, Arapahoe, and Douglas counties and the cities of Aurora, Brighton, Commerce City, Thornton, and the town of Parker. Affiliate, non-voting members are the cities of Arvada, Broomfield and Greeley, and Weld County. Ex-officio members are the Colorado Department of Transportation (CDOT), Denver Regional Council of Governments (DRCOG) and the Regional Transportation District (RTD). "Public Highway Authorities" are established by local jurisdictions under title 43 article 4 of state statutes.
